Patriots slot receiver Danny Amendola can feel the progress. The Pats’ three weeks of organized team activities close tomorrow, but the initial spurt of drills that allow the offense to practice against the defense have allowed some trends to materialize. The chemistry between Amendola and quarterback Tom Brady has been one of the most noticeable developments. It’s looked easy at times, and the offense has reached its highest level of consistency at practice when Brady has zeroed in on the middle of the field, and thus, Amendola. Last week, Brady applauded Amendola for his work ethic, so their rapport hasn’t appeared out of thin air. “We’re trying to get the most work we can in,” Amendola said yesterday at a Play 60 event when the Pats donated more than $50,000 in equipment and gear to the Roger Clap Innovation School in Dorchester. “It’s still early. Just trying to go from there and try to be the best we can be in the given time that we have.” The acclimation with the new outside receivers hasn’t been as smooth. Michael Jenkins, Donald Jones, Lavelle Hawkins and Aaron Dobson have flashed, but they haven’t achieved the same level of consistency as Amendola. But because the Pats completely reworked their receiving corps, Brady has been tasked with the challenge of doubling as a teacher, too. Amendola said it’s pretty easy to gravitate toward the quarterback when he shares his insight. “He’s a legend,” Amendola said. “He’s a football mind. He’s been around the game for a long time, and it’s fun to learn from him and play with him, pick his brain a little bit. It’s going to be a good year.” Amendola also walked into Gillette Stadium a step ahead of the other new receivers. Pats offensive coordinator Josh McDaniels ran the Rams offense in 2011, so he installed their system in the offseason before Amendola got injured in the opener and missed 15 games. “It’s a fun system to be in, and I’m looking forward to it,” Amendola said. The Patriots close their offseason program next week with minicamp before breaking until training camp opens in late July. That’s when chemistry translates to production, and Amendola is ready to roll. “It feels pretty good,” he said. “I’m ready to get the pads on. I’m ready to run around and start hitting people.”
